Abstract (en)
[origin: DE4434132A1] The invention relates to an ultrasonic welding process and an ultrasonic welding device for securing at least two superimposed wire ends to contact regions of electrical components, especially to contact regions of commutator bars for rotary electric machines, with a sonotrode and a device for initiating pressure. All the wire ends (16, 18) to be secured to at least one contact region (14) are to be pressed by the pressure (F) against the contact region (14) while at the same time the sonotrode (28) causes the lower wire end (16) to oscillate transversely to the pressure (F).
